Stacy, oliver, and jivesh each plan to put a certain amount of money into their savings accounts that earn simple interest of 6% per year. stacy puts $550 more than jivesh, and oliver puts in 2 times as much as jivesh. after a year, the amount in stacy's account is 2 times the sum of $212 and the amount in oliver's account. how much does each person initially put into his or her account? who had the most most money in his or her account after a year? who had the least? explain.

the answer is 772 because if you do 6+2+2+550+212=

answer is the third choice:

3x^5+4x^4+x^3+2x^2-10x-7=0

step-by-step explanation:

answer: c, the green line

step-by-step explanation:

there is no black line, eliminate b.

simple interest implies periodic payments, but the red line shows no payments, eliminate d.

simple interest has equal payments. if paid say every day, the graph is about a straight line (actually a stairstep).

the yellow line is not straight, eliminate a.

check: the green line is straight, answer is c.

simple interest with positive interest rate gives a straight line sloping up to the right. green line:

g(t) = $100 + ($200-$100) ÷ (20 years) × (t years)

= $100 + (4%/year) × ($100)(t years)

incidentally, the yellow line curving upward represents continuously compounded interest

y = $100 × 2^(t years / (14 assuming the yellow line hits $200 at 14 years. 2^0 is 1, so y(0) = $100; 2^(14/14) is 2, so y(14) = $200.
